From the docs:

You can create additional VPN connections to other VPCs using the same customer gateway device. You can reuse the same customer gateway IP address for each of those VPN connections.

  • Multiple VPCs in the same region cannot be connected with the same remote IPSec device. AWS doesn’t allow two connections within the same region to be connected to the same “Customer Gateway” (even when using multiple accounts). can you please take a look at this http://fortycloud.com/aws-virtual-private-gateway/ I am confused looking at this – chandra Jul 06 '16 at 17:37
